Effect of Planting Time, Mulch and Irrigation on the Growth and Yield of Garlic

M.A.K. Bhuiya, M.A. Rahim and M.N.A. Chowdhury
An experiment was conducted to study the effect of planting time, mulch and irrigation on growth and yield of garlic at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh during the period from October 1998 to March 1999. The objective of the work was to find out appropriate planting time and types of mulch and irrigation to get maximum yield of garlic. There were five planting time viz. October 25, November 9, November 25, December 8 and December 23 and seven types of mulch and irrigation treatments viz. Straw, water hyacinth, black polyethylene, transparent polyethylene, 10 days interval irrigation, 20 days interval irrigation and control (no mulch and no irrigation ) were used as the experimental treatments. The experiment was laid out in Randomized Complete Block Design with three replications. With the delay in planting time from Oct. 25 yield was chronologically reduced in later plantings. The highest bulb yield (3.9 t ha-1 ) was recorded when planting was done on October 25 which was statistically identical to November 9 planting (3.5 t ha-1 ). The lowest yield was obtained from December 23 (2.3 t ha-1 ) planting. Water hyacinth mulching yielded (4.27 t ha-1 ) best which was statistically identical with straw mulch (3.97 t ha-1 ). The lowest yield was obtained from white polyethylene mulch and control. Irrigation at 20 days interval showed better performance over irrigation at 10 days interval and control.
